Max Gordon Showalter, sometimes credited as Casey Adams, was an American film, television, and stage actor, as well as a composer, pianist, and singer. He appeared on more than 1,000 television programs. One of Showalter's memorable roles was as the husband of Jean Peters' character in the 1953 film Niagara.

Elizabeth Jean Peters was an American film actress. She was known as a star of 20th Century Fox in the late 1940s and early 1950s, and as the second wife of Howard Hughes. Although possibly best remembered for her siren role in Pickup on South Street (1953), Peters was known for her resistance to being turned into a sex symbol. She preferred to play unglamorous, down-to-earth women.
